I don't know if this will work for these ants, but my mom had an ant problem at her house and here's how she got rid of them. She mixed some Borax and maple syrup (or anything sugary, really) in the a water bottle cap. She left the cap out and the ants were attracted to it...they eat it and take it back to their "home" where eventually the Borax kills them. Ants are cannibalistic (LOL) so they will eat the dead ants and some Borax as well, killing them off. It really worked well and got rid of the ants.
